Thank you very much for your answer, somehow the exception did not work, but I guess it is ok it is not a shared storage, it is a dual sas port external JBOD box.

Actually, to enable sas support, you can do this:
# cat /etc/multipath/conf.d/enable-sas.conf
blacklist_exceptions {
protocol "scsi:sas"
}

It should be detect it this is shared storage that you want to use in oVirt
It should not be detect if you have local disk using sas.
So we really cannot know.

oVirt does not officially support sas, but this should work:
protocol "(scsi:fcp|scsi:iscsi|scsi:sas)"
The best way to configure it is to add a dropin configuration file:
$ cat /etc/multipath/conf.d/my.conf
blacklist_exceptions {
protocol "(scsi:fcp|scsi:iscsi|scsi:sas)"
}
